Different types of zinc coatings for different purposes…
Hot-dip galvanizing is a powerful way to protect steel from corrosion.
What determines the lifespan of a hot-dip galvanized product is the thickness of the zinc layer. This trailer has a steel structure made of batch-galvanized steel, while the protection over the wheel arches consists of continuous galvanized thin sheet steel with a significantly lower coating thickness, that now has been consumed. Different types of zinc layers are suitable for different products, but this is a very clear example of the influence of layer thickness on the sustainability of a galvanized product. If a long maintenance free lifetime is desired, batch galvanizing is the right choice!
